Imagine you have a toy box filled with all your favorite toys. You love playing with them, but sometimes you want to share them with your friends. The same is true for grown-ups and information about how their country works.
People who work for different governments sometimes find out about things that are going on that might affect you or your family. They might learn about how many people were sick or how much money the government spent on something important.
An international open government data conference is like a big meeting where people from different countries come together to talk about the information they have learned while working for their government.
They discuss ways to share this important information with other people around the world. They want anyone to be able to see and use this information, just like how you might want your friend to play with your toys with you.
The goal is to help everyone make informed decisions about important topics like the economy, health, and education in their own country and around the world.
